between the organ systems of cephalopods and those of less ambitious molluscs. Octopus does, as we would predict, live close to the limits set by its own physiology. The circulation, to take one example, is barely adequate for such an active animal, mainly because of the absence of any system for pack aging the blood pigment; haemocyanin in solution is a poor oxygen carrier. Cephalopod blood can transport less than 5 millilitres of oxygen per 100 ml of blood (compared with about 15 vol% in fish) and the whole supercharged system of triple hearts, high blood pressure and pulsating blood vessels succeeds only in returning blood that retains less than 30% of its dissolved oxygen by the time it reaches the gills. This at rest; the effect of exercise is immediate and surprisingly long lasting even in octopuses as small as 300 g, which must very swiftly run into oxygen debt when they flee from predators or pursue their prey (Sections 3.2.2, 3.2.4). Digestion, too would seem to be limiting. As with other molluscs, digestion in Octopus is based on secretion absorption cycles by a massive diverticulum of the gut, an adequate system in a less hectic past, but scarcely appropriate in a predator that must be an opportunist in the matter of feeding. Octopus feeds mainly at night, and spends a great deal of every day sitting at home.

Employing the clear, student-friendly style that made previous editions so popular, Insect Physiology and Biochemistry, Third Edition presents an engaging and authoritative guide to the latest findings in the dynamic field of insect physiology. The book supplies a comprehensive picture of the current state of the function, development, and reproduction of insects. Expanded and updated, this third edition continues to challenge conventional entomological wisdom with the latest research and analytical interpretations. It will appeal to undergraduate and graduate students and to working scientists in the biological sciences who need to possess a firm knowledge of the broad principles of insect physiology. See What’s New in the Third Edition: New chapters covering biological rhythms and insect symbioses Adds references from the last several years to bring each chapter up to date Provides new review and self-study questions that aid in distinguishing the most important information and concepts References to websites where illustrative materials have been provided by scientists and contains approximately 2,600 citations Twenty-four pages of color illustrations with new illustrations that emphasize genetic and molecular developments in insect biology Update of the rapidly developing area of postembryonic development of insects, especially the role of the juvenile hormone in insect development While this edition provides new information and significant updates, it also maintains all the features that made previous editions so popular, such as citations that enable you to get to the primary literature easily and understand the thinking, experimentation, and techniques that have enabled the current understanding of the physiology of insects. And clear writing with technical terms explained in the text where they occur. With more than 250 illustrations to help explain physiological concepts and important anatomical details, the book remains the most easily accessible guide to key concepts in the field.

Advances in Marine Biology was first published in 1963. Now edited by A.J. Southward (Marine Biological Association, UK), P.A. Tyler (Southampton Oceanography Association, UK), C.M. Young (Harbor Branch Oceanographic Institution, USA) and L.A. Fuiman (University of Texas, USA), the serial publishes in-depth and up-to-date reviews on a wide range of topics which will appeal to postgraduates and researchers in marine biology, fisheries science, ecology, zoology, oceanography. Eclectic volumes in the series are supplemented by thematic volumes on such topics as The Biology of Calanoid Copepods. - Rated "Number 1" in the highly competitive category of Marine and Freshwater Biology by ISI in the 2000 ISI journals citation report - Maintains an Impact Factor of 3.37, the highest in the field - Series features over 35 years of coverage of research
